Need prop for 35hp Evinrude

[jwc949]

I have a 16' lowes aluminum boat with a 1981 Evinrude 35hp. I have no tach but the engine does not like to rev when in gear. It also is very slow. I have been unable to see what the prop is that is on it( no markings). What would everyone recommend for more speed? We do not troll with it. We would like to go a little faster as I think the the trolling motor is faster right now. Two grown men and fishing gear sometimes three is the load. Do not care about how quick of a hole shot just would like to get there faster. Thanks!

Does there seem to be something wrong mechanically or it just is not fast. If that is the case you will want to change the propeller to a low pitched. This will help you plane out. If it is mechanical, what symptoms does it provide.
